It takes me about 3 minutes to feed/water 4 gallons into 4 pots out of my 5 gallon bucket. (A 4 gallon bucket of water is all I can comfortably carry) And that’s with stopping and waiting for the water to leach down too. I only use this method when my plants are tied down in their final pots. I get a good 1/2” stream of flow don’t know GPM but it’s quick.
